Waste minimization and process integration applied to the retrofit design of chemical processes
- Oklahoma State Univ., Stillwater, OK (United States)
The chemical processing industry is faced with a need to manufacture quality products while minimizing production costs and complying with all safety and environmental regulations. As a result of the constant change in regulations, the Pollution Prevention Act, and the increasing pollution control costs, end-of-the-pipe treatment is no longer feasible or recommended. Therefore, a recent approach is to apply source reduction instead of the end-of-the-pipe treatment. The purpose of this paper is to present the development of a methodology for waste minimization and the reduction of energy consumption in the chemical processing industry (CPI) by the modification of existing processes. This task was accomplished through the use of ASPEN PLUS{trademark} a sequential modular simulator and the combination of a hierarchical procedure for generating process alternatives, process integration for analyzing energy efficiency, and a mathematical programming approach for process optimization (MINLP). The methyl chloride process has methylene chloride, chloroform, and carbon tetrachloride as byproducts. These chemicals are regulated by the CAA, CWA, RCRA, and HON. This process was used as a case study. The significance of this work lies in the development of a general methodology to identify potential pollution prevention projects in the CPI by using economic, energy, and environmental criterion.
